Firefox Community Forum

Firefox lived on my computer for three days. On May 30th I installed the latest version of Firefox Developer Edition. Today when I launched my browser I saw a page notifying me that my version of Firefox is the latest [152.0b6 (64-bit)]. All installed extensions disappeared, the connected profile was deleted, the .mozilla/firefox directory contained only the newly created profile... No history, no bookmarks... No crash reports...

What happened? Now I'm afraid to sync the browser with my phone, in case it clears all my passwords.

I have now been prompted 10 times today to make firefox by default browser - it has been my default browser for years. Each time I go to windows settings to check - it does not show me that firefox is the default. I select default for firefox but still is doesn't follow the command. I did manage to get it to accept the default command ONCE today but when I rebooted the laptop it went back to prompting me to make it the default all over again - must be 10 times now. This is infuriating. Could this issue be due to a VPN I have (NORD)? Having said that, I have tried 8 times to set the default while NOT connected to the VPN. What can I do?

I have recently installed Firefox on a new Laptop computer and on startup of Firefox the first page typically shows in the middle 7 or so icons for various accounts or processes, some of which are accounts I have recently accessed. BUT some of them are foreign ie. I have not used or accessed. AND it seems that some accounts/processes that I have & frequently used are NOT shown. How can I manage it so that my REAL FAVOURITES appear?

I can't log into an email from my health site called MyMercy to get lab reports, etc., using Firefox; Have to switch to Google Chrome to do it. Is Firefox aware of this issue? Please respond [edited email from community support forum]

I downloaded the Firefox ESR for my High Siera OS, but I still get the message that Firefox is no longer supported, Why??? Just let me know what I need to do so I can use the browser without worry.

I have a MacPro 2012, updated to the max. I'm retired, and by budget does not allow for a new computer.

Thanks. Doina Paraschiv

One Home/House. Two PCs. a. WINDOWS 1O b. LINUX 22.3 Both share One Mouse One Keyboard One Monitor. I have a FIREFOX account and have joined both PCs to MOZILLA. I have activated, deactivate and successfully used FIREFOX SYNC. I keep getting emails from MOZILLA stating that someone else signed on to my email acct. and a MOZILLA supplied a 6 digit code to confirm. I know it was me, so I confirm using 6 digit code and no problems. My question is. Who, How or can I inform so MOZILLA/FIREFOX recognizes both PCs. Also. Have been thinking about purchase of a YUBIKEY/KEYs for security. I know, for loss prevention, it is best to purchase 2 Keys. But can a single YUBIKEY be shared on both PCs. Or, do I need to purchase separate keys for each PC? So 4 Keys... 2 Keys for the WINDOWS 1O and 2 keys for the LINUX PC?

recently when trying to book a flight on American airlines i get a "not authorized to access the server". No problem logging in. has been happening on other web sites as well. seems somewhat random.

My FFox browser has been invaded by PINK EVERYWHERE Get rid of it in the browser. The suggestions do not seem to do anything to get rid of this horrible color. TFFox 151.0.2 64

Black and white works fine in Menu Bar and web addresses when you finally get your act together.

when trying to log into bank account it goes to a screen that says "performing security verification" when i tick box to verify you are human it goes into the spinning wheel and then continues in a loop with the verification process all over again .continuously .

Since the latest Firefox update, it has frozen the app & crashed my computer multiple times within a few days; it has also caused problems logging into my primary bank account ("access denied") but has nothing to do with the bank (I called the bank; no problems there, but they suggest using Chrome browser. NO WAY!) Every time Firefox has updated the past few months, it has interfered with my password vault’s proper functioning {Last Pass}. I am using a late 2012 Mac mini, running OS 10.15.1 (the newest acceptable OS for my computer). I attribute some of the problem to their adding a number of new features without making certain the basic app is stable.

Ok, I screwed up.

I was trying to solve a problem I've been having with regular releases of Firefox and it occurred to me try the ESR release so I downloaded and installed it. The good news is that it solved my problem, the bad news is that I just barrelled into it without thinking, assuming that my logins and bookmarks would just transfer over like with regular releases. They did not. It turns out I should have made a backup of those things first and I can't open the old regular release of Firefox to properly back-up those things now. Oops.

I've been reading lots of forum posts here and elsewhere trying to get those files into ESR and I haven't been successful. From the profile manager I've located the profile that still contains that info and I've tried:

Copying and pasting the "logins.json" and "key4.db" files from the "default-release" profile into the ESR profile which didn't work.

From "about:profiles" I also tried to "launch profile in a new browser" of the default-release profile so I can open that profile and properly back-up bookmarks and logins but I get a prompt to create a new profile which I tried several times and only resulted in several profiles of the ESR release.

Then it occurred to me that If I could just delete all instances of ESR and open the old default-profile then I could back-up the logins and bookmarks, THEN download and install ESR again and import those files but before diving into that I need to make sure that won't loose my original default-release profile info.

So experts, does that sound reasonable? Delete all instances of ESR so I can open the regular Firefox? What's the best way of going about that?

Thank you.

If I enable a chatbot in the sidebar, does that bot have access to the pages I'm viewing - for example, on a continual basis, or only if I prompt it to read a page? Does it have access to the URLs I'm visiting, etc.

The main help page explaining about the chatbot sidebar does not address this.

Trying to recover Hotmail account pop up by Mozilla says to insert security key into USB. i don't have one. Never had one. Restricts me from continuing recovery. Can you help please.

How do I stop this page from coming up several times a day. I have already set FireFox as my default browser, several times, but to no avail. I've careful followed your instructions. I dislike MS and have used FF for years. If this doesn't stop, I'll search for another browser that hopefully behave. I have set it on 4 computers, 2 Win 10, 2 Win 11.

By the way, the computers show FireFox twice, but only one actual installation.

Please do better!
